ATTD RN EYS Patented May 30, 1944 UNITED STATE PATENT OFFICE 1 Claim.

My invention relates to the ventilation of buildings, and has among itsobjects and advantages the provision of an improved rain shieldapplicable to windows of standard Construction.

In the accompanying drawing:

Figure 1 is a perspective View of a rain shield in accordance with myinvention;

Figur-e 2 is a cross sectional View of a window sill illustrating myinvention applied thereto;

Figure 3 is a horizontal sectional View of a window frame illustratingthe rain shield in position;

Figure 4 is a perspective view of a different form of rain shield; and

Figure 5 is a cross sectional View of the window sill illustrating theform of Figure 4 applied thereto.

In the embodiment selected for illustration, the rain shield of Figure 1may be stamped from thin sheet metal to provide channels n contoured tofit between the parting strips l2 and !4 of the usual window frame IS.The lower edge !8 rests on the window sill 28 with the face margin 22lying against the usual strip 24 on the sill 20.

The rain shield includes a wall or deflector 26 inclined to the verticaland connected with the Channels H] through the medium of end walls 28which are so located as to fit between the two strips !2. The lower edgeof the wall 26 extends down to the margin 22, with the marginsufiiciently wide to provide sufiicient clearance between the strip 24and the wall 25. In many windows, there is considerable clearancebetween the sash rails 3!) and the strips l2 and !4, as well as betweenthe faces 32 of the sash rails and the window frame IS. Under suchconditions, the sash rails 30 may slide freely in the channels n so thatthe window sash may be adjusted vertically to different positionsrelatively to the rain shield. The wall 26 is positioned inside the roomand constitutes a deflector for rain which would otherwise be blown intothe room. In the event that the sash rails 38 fit tightly inside theframe IG, the window sash may be lowered to an engagng position with thechannels m, which provides ample rain shield protection in most cases.Since the rain shield ts loosely in the window frame, the shield iseasily placed in position as well as removed for installation in otherwindows requiring such protection. While the rain shield fits looselyinside the window rame, the rain shield is held securely in placethrough its engagement with the window sash.

Figures 4 and 5 illustrate a different form of Construction, wherein thechannels l0 are eliminated and the end walls 32 are provided withnotches 34 into which the lower cross rail of the window sash may belowered to hold the rain shield in place. In the Construction of Figures4 and 5, the end walls 32 are sufficiently wide to span the strips l2and !4.

With out further elaboration, the ioregoing will so fully illustrate myinvention, that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service.

I claim:

in a window including a window sash slidable in grooves in a frame, arain shield of sheet metal comprising a flat elongated rectangulardefiecting wall, a relatively narrow strip formed integral with thebottom edge of said wall and extending therefrom at an obtuse angle, andan end wall formed integral with each end of the defiecting wall and thestrip, each end wall extending at a right angle to the defiecting walland strip and across the sash groove at each side of the window 'frameand having a rectangular cutout in its top edge and spaced inwardly ofthe outer end thereof for snug engagement about the lower rail of thesash.
